I live at the door of the dormitory, anyone who knows Feng Shui can come in
This question has nothing to do with Feng Shui. In so many school dormitories, there are always people living near the door. When I was in college, I lived near the door for four years (there was also one semester when the window seat was given up and I took the initiative to move to the door).
The disadvantages of the door are the cold wind in winter and the noisy opening and closing of the door. My opinion is to sleep with your head against the wall on the side of the door, so you won't be directly exposed to the wind. You can put a stack of books outside the bedside to block the wind. Secondly, people outside the door will not directly see their faces when they glance at them when they pass by. Secondly, it is convenient to close the door (it is inevitable that some people always forget to close the door). You can hang a picture on the side of the bed against the wall, which is good for Feng Shui.
